Question

select the correct answer.
which of the following represents a constant from the expression given?
$15x^2 + 2x + 9$

a. 24
b. 9
c. 2
d. 15

Explanation:

Step1: Define a constant

A constant in an algebraic expression is a term that has a fixed value and does not contain a variable.

Step2: Analyze the given expression \(15x^{2}+2x + 9\)

• In the term \(15x^{2}\), \(15\) is a coefficient (it multiplies the variable \(x\) raised to a power).
• In the term \(2x\), \(2\) is a coefficient (it multiplies the variable \(x\)).
• In the term \(9\), there is no variable, so it is a constant.
• Option A, \(24\), is not present in the given expression.

Answer:

B. 9
